ARTlIFICIAL DENTURE. l

' Application filed August 4, 19253. iSerial @0.3553112 following is aspecification.

My invention relates to articial dentures and is applicable particularlyto dental attachments for plates and bridges.

My invention relates to the construction of the connection between abridge, plate or other form of artificial denture containing artificialteeth and a clasp or other removable means of connection to a naturaltooth. My attachment makes a movable removable connection for a bridgeto natural teeth and also permits the bridge to be removed readily fromthe mouth. My attachment, therefore, is adapted to permit anvartificialdenture to be adjusted vertically with respect to the teeth to which itis attached and to make a pivotal or rotatable connection with the teethto which it is attached. My construction eliminates stress of the plate.It, therefore, also enables the artificial denture to be set at thenecessary angle with the natural teeth to which it is connected. Afurther object of my invention is to enable the dentist or dental supplymanufacturer to complete the construction of the parts of an artificialdenture and then to attach the parts permanently together.

One embodiment of my invention is shown in the accompanying drawings inwhich,

Figure 1 is a side elevation conventionally representing a part of thelower jaw with some natural teeth and a bridge provided with artificialteeth attached tothe natural teeth with my attachment;

Figure 2 is a top plan view of the part shown in Figure 1; Y o

Figure 3 is a perspective of the two parts of my attachment separated,one part being attached to a conventional clasp;

Figure 4 isa side elevation of my attachment and a clasp one part of theattachment being placed at an angle to the other part thereof;

Figure 5 is a section on the line 5 5 of Figure 4 showing the connectionof the attachment with a clasp and an artificial tooth;

Figure 6 is a section on the line 6 6 of Figure 5.y

I have shown in the drawings a conventional part of a lower jaw 1 andnatural teeth 2 to which is attached a bridge 3 containing artificialteeth 4, the bridge being attached to the natural teeth by clasps 5.These clasps 5 may have a cusp 6 if used with a tooth requiring such apart.

The artificial teeth may be secured to the bridge in any of the wellknown ways and may have a metal bar 7 on the sides of the end teeth.

The part of my attachment 8 which is soldered, sweated, cast orotherwise attached to the-clasp may be hollow and rectangular in shapeand until completed will have one end 9 open and a slot 10 in one sidethereof. It will be evident, however, that the part 8 may be of othershapes which would have the same functions as the shape shown. Y Thesecond part 11 of my attachment is secured to the bridge in any desiredmanner as by soldering, sweating, or casting it to the plate 7. The part11 has attached thereto and spaced therefrom as by a pin 12 a circularhead 13. The head 13 is adapted to slide in the rectangular part and tomake a connection which is pivotal and enables the second part and thebridge to be adjusted vertically with respect to the first part and theclasp. After the parts 8 and 11 have been joined by sliding the head 13into the opening 9, the lower part of 8 is bent as shown in Figures 4and 5 to close the opening 9. The bent part of 8 may be then soldered orotherwise finished fiush to close the bottom of the part 8 the same asthe top thereof.

It may be pointed out that although I have shown my attachmentconnecting a bridge having three teeth, it is evident that my attachmentmay be used to connect one as well as a plurality of artificial teeth toa natural tooth or teeth. j

It is also evident that my movable removable attachment may be appliedto one side only of a bridge or plate if such a construction is desired.

It may also be pointed out, therefore, that my connection enables anartificial denture to move buccally, lingually and vertically.

Having described my invention what I claim and desire to protect byLetters `Patent is,

1. An attachment for artificial dentures comprising a hollow partattached to means removably connected with a natural tooth,

said part having a slot in the side thereof and a second part attachedto a denture body, said part comprising a plate having a circular memberattached thereto and separated therefrom, whereby a slidable and 5`pivotal connection is formed between said parts.
